Is it because people are committing more crime than the original offense?
Nah. They would never do anything like that.
As everyone knows, all police are paragons of moral excellence in every country in the world at all times.
Governments have definitely never, ever gone after innocent protesters.
</sarcasm>
i.e. how skewed are different professions w.r.t. morals?
Do you think lawyers are worse? Politicians? The Media? Where do police fit into this spectrum?
Are all police bad? What percentage?
<perspective> (you can close this tag if you wish)
With power comes a responsibilty to be better than others, and if that's not something you can count on, which it isn't, we need to protect others.
